IMPROVEMENT kIN CHURNS.

The Schedule referred to in Ithese Letters Patent making part oi thesame.

To all whom 'itmay concern Be it knoim that I, A. P. BRYsON, ofProspect, in the county of Butler, and State of Pennsylvania, haveinvented an Improved Ghurn-Dasher; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, making part of this specication- Figure 1being a side view ofthe dasher'.

Figure 2, a central vertical section of the same.

Figure 3, a bottom dew thereof.

Like letters designate corresponding parts in all the figures.

The form of the dasher A is concave on its under side, its externalappearance being that shown in the figures, or any` approximationthereto. It has, externally, lnear the base, a hexagonal or otherpolygonal form, to the facesof which are attached the wings an.. TheseWings are placed obliquely, in the manner substantially as represented,for the pulpose of giving a rotary motion to the -dasher on a verticalpivot, when the handle B receives a reciprocating motion in the ordinaryWay. This vertical pivot allows the dasher to turn freely in bothdirections.

Small apertures, b b, are formed obliquely through the shell of thedasher, from the concave chamber within, through which air and cream maypass, as the dasher moves up and down.

The Wings may be perforated with openings 'c c, to assist in cutting thecream.

The oblique position of the Wings gives the dasher a rotaryreciprocating motion, when the handle is moved up and down, thuscreating increased agitation in the cream.

As the dasher is lifted-out ofthe cream at each'up- 'Ward stroke, itschamber lls with air, which is forcibly expelled through the aperturesat the downwardstroke, thus not only increasing the agitation, butallowin g the air to commingle intimately with the cream.

What I claim as my invention, and desire to secure by Letters Patent,is`

The combination and arrangement of the oblique wings a c, and concave,perforated, revolving dasher, A, substantially as and for the purposeherein4 specied.

The above specication of my improved churn-flasher signed by me, this18th day of August, 1868.
